Those bas***ds! I sent them a dispute in early June for 2 ca accounts. I just received a letter from the ALMIGHTY EXP, claiming on one CA account, they already investigated and will not the reinvestigate. The second CA, they claimed I did not give them enough info. to investigate. Attached to my dispute was a letter from the OC of the first CA account stating I was never billed at the correct address... I never knew I had a balance of $30 (cat bill). For the second CA, I disputed as incorrect and asked Exp to refer to the letter from the CA...... a letter to delete the account. This is so frustrating because I am planning on applying for a home mortgage next month and this has thrown everthing off. I dispute two CA accounts with EXP, attach letters from OC and CA, AND THAT IS NOT ENOUGH for EXP to delete or even investigate? What should I do?
